Description
Description
Overview
GAOTek handheld optical variable attenuator is used for continuously variable optical signal attenuation. As the attenuator is used in the laser system for the online testing, there, therefore it can be used in the digital system of communication devices (such as: PHD, SDH) and also in the system of adopting analogue modulation (CATV).
Features
- stepwise attenuating by circumgyrated dial: attenuating step 0.05dB
- Provide with the function of displaying dB and dBm attenuating value
- Alternative function of 10 minutes Auto-off without operation
- Memorizes attenuating values and steps for easy restoration
